UltraCompare 15.1 released
Get to your compare faster with improved explorer integration!

Comparing files and folders straight out of Windows explorer just got easier with completely re-engineered Windows explorer integration in v15.1. Fire off a compare of selected items in a single click, or review and set compare targets before launching. UltraCompare's context menu functionality in v15.1 hasn't just been enhanced – it's been completely re-thought for maximum usability and efficiency.

Other additions to UltraCompare v15.1 include a split explorer pane, improved internal algorithms for matching up text in text compare, and a hefty installment of maintenance. Read on below...

New in v15.1: Re-engineered shell integration


UltraCompare's explorer integration now includes 2 modes: basic and advanced. Both modes are available within the context menu and are not mutually exclusive.

Basic explorer integration allows you to select up to 3 files or folders, right-click, and fire off a compare. It's that simple. No frills, no bells, no whistles — this option is provided to get you from point A to point B as quickly as possible.

Advanced explorer integration allows you to manually specify which files or folders are loaded into which compare frames. This is useful if your items to be compared are in different folders, or if you need to select one item for compare now and another later. Although we call it "Advanced", it's incredibly simple to use: just right-click the item you want to queue for compare, go to Manually select items and then choose your desired compare frame. Once all compare targets are loaded, click one of the options to Compare as Text or Binary.

With this option enabled in Options -> Configuration -> Shell Integration, UltraCompare automatically loads your queue with selected items, ignoring items that are already queued. Items are added in a first-in, first-out order so that older items are pushed out of the list to make room for those more recently clicked.


New in v15.1: Split explorer pane

UltraCompare now shares the same split explorer pane interface as UltraEdit and UEStudio. You can sort the files and folders in the lower pane by name, date, type, or size.

The split explorer pane is optional; use the toggle icon at the top right to enable or disable it. You can also create and load file extension groups for filtering the file listing.
